BROODEB.

Specioltion o! Lettersv Patent.

Patented Jan. 28, 1913.

Application led February 16, 1912. Serial No. 678,059.

To all whom it may concern Be it known that I, MARTIN TREWHITT, asubject of the Kin of Great Britain, and resident of Cyrvllle Road,Hurdmans Bridge, city of Ottawa, Province of Ontario, Dominion ofCanada, have invented certain new and useful Improvements in Brooders,.and do hereby declare that the following is a full, clear, and exactdescription of the same, such as will enable others skilled in the artvto which it appertains to make and use the same.

My invention relates to improvements in brooders and the objects are toprovide a simple and sanitary form of brooder that will be light, cleanand provided with plenty of fresh air, that may be easily transportedfrom one place to another, and which will require no lamp or otherattachments likely to require careful attention, and which will on theinterior present no corners or other recesses likely to collect dirt.These and other objects are accomplished by the improved constructionand arrangement of parts hereinafter described in detail in theaccompanying specification and drawings.

In the drawings, Figure 1 is a perspective view of the brooder. Fig. 2is a longitudinal section therethrough. Fig. 3 is a cross section. Fig.4 is a sectional detail through the stand for supporting the heatingbricks. Fig. 5 is a sectional detail of one of the interior corners.

Referring to the drawings, A represents the walls ofthe brooder made ofsuitable light stiff material such as l inch lumber, suitably stayed onthe interior, and lined wilth a warm durable substance such as linofe t.

B represents the top which is made in two sections 10 and 11, thesection 10 being hinged to one wall of the brooder while the section 11is hinged to the section 10. The section 11 is designed to cover thebrood chamber C while the part 10 covers the run chamber D, the interiorof the brooder be- 'ing divided into these two lchambers by means of apartition E which has an aperture 12 for vthe passage of the chickensadapted to be controlled by a door 13 which swings down into the runchamber.

To prevent injury 4from crowding, and also to facilitate cleaning of thecornersv of the brood chamber the said corners are rounded inwardly bymeans of strips of outer surfaoesfas shown. The run chamber is providedon the side with a Ventilating opening 15 adapted to be closed b ahinged i window 16 which is retained in a justed position by means of achain 17 leading from the window to a hook 18 on the side Wall. Thewindow 16 is formed with a glass portion 19, and a cheese-cloth portion20 thus giving both light and ventilation.

A door 21 is provided on the run chamber adapted to swing downwardly andform a run-way, either into an open field or into a wire run as may bedeemed desirable.

The heating of the chamber is effected through novel means which I havedevised, and which comprise a plurality of bricks 22 adapted to beheated and placed on a stand F which may be placed within the runchamber, this stand comprising suitable legs 23 and a perforated top 24preferably of metal, such as galvanized iron. The lower part of thisstand is formed with means to warm the 'chicks and keep drafts away fromthe same. These means comprise strips of fiexible heat absorbingmaterial such iaslannelette strips 25, which are supported from thestand by wires 26.

The stand F is adapted to be lifted into `and out of the brood chamberso that for cleaning purposes the brood chamber may be left absolutelyopen and the stand may be hung uip in the sun and wind to purify. Inusing t e heating arrangement the bricks are made hot and placed on thestand in the brood chamber just before'the chickens go to roost. Thebricks will 've ofi' a certain amount of heat to the chickens until theyreally get settled down for the night after which the animal heat givenofi" by the animals themselves will keep them comfortably warm for theremainder of the night and the flannelette dropping to their backs andbeing of a heat absorbing character will take the place of the motherhen.

It will be seen that the use of an excessive amount of artificial heatis avoided in the present invention. The use of too much artificial heatlowers the vitality of the chickens and makes them more susceptible todisease. The bricks being heated will be very dry and will consequentlyabsorb all moisture from the breathing of the chickens and also thatgiven off from their bodies. Suitable Ventilating 'openings 27 may beprovided in the ends of the endwalls.

In order to enable the brooder to be easily moved about and thus givethe chickens a change of ground, and to enable this to be made withoutmuch labor I provide the following means, namely: a caster wheel28having a stock adapted to be inserted intov a suitable socket 29 on theend of the brooder and a transverse axle 30 having wheels 31, the saidtransverse axle being adapted to fit in bearing recesses'32 on the sidewalls of the broeder, said bearing recesses being normally closed bygravity slides 33 operating in guideways 34, said slides being adaptedto ie d upwardly when the shafts ,are inserted eneath them.

When it is desired to move the broode the end is lifted up and the axleforced along with the foot until it comes into position beneath thebearing slots into which it will drop. The caster wheel is then placedin position when the brooder may move to wherever it is desired, andtwisted and turned into any position.

It 4will be seen that as the wheels and axles are detachable a singleset of axles and -wheels. would vserve for a number of broeders. It willalso be seen that the brooder may be cleaned by lifting the top.,

. other heat absorbing and radiating material of a similar character tobrick might be used in place of the brlck and the term heat absorbmg orradiating element is intended to denote any lsubstances which willabsorb a uantity of heat, which it will afterward ra iatewhen placed inthe broeder. As many changes could be made inthe aboveconstruction andmany apparently widely different embodiments of my invention, within thescope of the' claims, constructed Without departing from the spirit' orscope thereof, it is intended that all matter contained in theaccompanying speci-v on the top of the stand, means spaced from lsaidtop and below the same for receiving protecting means to contact withthe chickens, and retain their animal heat.

In witness whereof I have hereunto .set

my hand in the presence of two witnesses. MARTIN TREWHITT.
